SJ Medical
Established in 2015: Leading the frontier of medical sampling and interventional care.
Hangzhou SJ Medical Co., Ltd. is a premier high-tech enterprise dedicated to the research, development, manufacturing, and commercialization of vascular interventional medical devices and advanced sampling systems, including Universal Transport Medium (UTM). We focus on providing safe, reliable, and innovative solutions for healthcare providers worldwide, bridging the gap between clinical needs and manufacturing excellence.
Over the years, SJ Medical has developed a comprehensive product portfolio covering key areas of vascular intervention. Its offerings span from various types of balloon catheters for coronary and peripheral applications to supporting access and diagnostic devices, as well as advanced stent systems. Through continuous innovation and strong R&D capabilities, the company has obtained multiple patents and international certifications, laying a solid foundation for sustainable growth in both domestic and global markets.
The global demand for high-quality Universal Transport Medium (UTM) has seen an unprecedented surge. As molecular diagnostics become the gold standard for pathogen detection, the industry has shifted toward stabilized, room-temperature-stable media. Today, UTM is not just a liquid; it is a critical bio-preservation system used in hospitals, CDC labs, and remote testing sites across Europe, North America, and emerging markets.
The future of UTM lies in automation compatibility and Inactivation capabilities. We are seeing a trend where procurement officers prioritize media that can preserve RNA/DNA integrity while simultaneously neutralizing infectious agents to ensure laboratory technician safety. Furthermore, the integration of 3D-printed flocked swabs with UTM tubes is becoming the standard for maximized sample elution.
International buyers—ranging from Ministry of Health tenders to private diagnostic distributors—require OEM flexibility. There is a growing need for "White Label" solutions where manufacturers provide the CE-marked media while the local distributor applies their branding. Supply chain resilience, consistent pH levels, and antimicrobial additives are the top three technical requirements in 2024 procurement cycles.
Tailoring Medical Grade Transport Solutions to Every Environment
In high-throughput clinical settings, our UTM systems ensure that viral samples remain viable during the critical transit time between the ward and the molecular lab. Our tubes are designed with specialized internal cones to prevent sample loss during centrifugation.
For international transit points, rapid and stable sampling is vital. Our room-temperature stable UTM eliminates the need for expensive cold-chain logistics, allowing for widespread deployment in airports and seaports across diverse climates.
For genomic sequencing and viral surveillance projects, our media provides a nutrient-rich environment that prevents the degradation of delicate viral envelopes, ensuring high-fidelity results in PCR and NGS applications.
Governments and NGOs utilize our high-volume OEM manufacturing capacity to build national stockpiles. Our long shelf-life (up to 24 months) makes us the preferred partner for long-term emergency readiness.
SJ Medical operates a modern manufacturing facility with a total area of approximately 5,000 square meters. The factory is built in accordance with GMP standards and features a high-standard cleanroom environment, including a million-class clean workshop with localized hundred-class areas for critical processes. This ensures that every batch of Universal Transport Medium or vascular catheter is produced under the most stringent sterility controls.
